The Center for Addiction Treatment opened an outpatient facility on its campus in the West End on Thursday, and 21 jobs are to be filled as it ramps up services at the new building.

CAT expects the Spaulding Recovery and Family Care Building at 834 Ezzard Charles Drive to help thousands of drug addicts annually, and it also will provide a setting for new doctors who are in residency programs as well as physician assistants to receive training in how to care for patients in recovery.
